2. Description of the Related Art Recently, various medical practices have been performed in the medical field, and recently, infections from patients, especially among medical staff, have become a problem. For example, the infectivity of viruses such as hepatitis B and AIDS is extremely strong. As a conventional waste treatment device, for example, there is one described in Japanese Patent Publication No. 450020. In this waste treatment device, medical waste such as an injection needle is heated or immersed in a chemical solution for sterilization, and then crushed to treat the waste.

[0003]

However, in such a conventional waste treatment apparatus, medical waste such as an injection needle is simply heated or immersed in a chemical solution for sterilization and then crushed. Therefore, there is a problem that the cost is high because the structure for heating is complicated and a chemical for dipping and disinfecting in a chemical solution is required.

On the other hand, in order to reduce the cost, for example, if a chemical is not used, only heating is performed. In this case, if the degree of heating is poor, bacteria, viruses and the like cannot be sterilized sufficiently. was there. Further, since medical waste is heated or soaked in a chemical solution for disinfection, there is a problem that the disposal process is slightly slow.

Therefore, an object of the present invention is to provide an injection needle sterilizing and crushing apparatus which has a simple structure and can safely and quickly dispose of an injection needle at low cost.

[0006]

In order to achieve the above object, an apparatus for sterilizing and sterilizing an injection needle according to the present invention comprises a sterilizing means for electrically incinerating by applying a predetermined voltage to the injection needle, and the injection needle. It is characterized by comprising crushing means for crushing and storage means for storing sterilized and crushed injection needles.

In a preferred embodiment, a start switch for starting the sterilizing means and the crushing means is provided. The crushing means has a cutter blade that is decelerated by a motor, and crushes an injection needle or the like by rotating the cutter blade. The storage means is characterized in that it can be freely taken in and out of the sealed container, and receives and stores the falling of the injection needle sterilized and crushed by the sterilization means and the crushing means, respectively.

[0008]

In the present invention, a predetermined voltage is applied to the injection needle by the sterilizing means to sterilize it, and at the same time, it is crushed by the crushing means having a cutter blade that is rotated by being decelerated by a motor, for example. It Then
The sterilized and crushed injection needle is stored in the storage means.
The injection needle stored in the storage means is taken out at any time and discarded. As described above, the voltage is sterilized all at once, and at the same time, the particles are crushed and no chemicals are used. Therefore, the injection needle can be safely and quickly disposed of with a simple structure and at low cost.

A method of using the injection needle sterilization crushing apparatus 1 having the above-described structure will be described. Used needles are contaminated with bacteria. Now, bring the used injection needle to the installation position of the injection needle sterilization crushing processing apparatus 1. Next, the power switch 4 is first turned on, and then the start button 3 is pressed. As a result, the contact 3b of the start button 3 is turned on, the motor 26 is started, and its rotational force is transmitted to the cutter blade 25 through the reduction gears 27 to 29 in sequence, and the cutter blade 25 is moved in the direction indicated by the arrow (FIG. 2). Rotation (see 1)
4 rotations per second).

At this time, the contact 3a of the start button 3 is simultaneously turned on, and the voltage from the battery 24 is applied to the closing electrode 22 and the cutter blade 25. Then, the used injection needle is charged from the charging port 6 formed in the upper part of the casing 2,
The cutter blade 25 is inserted into the groove 25a formed on the outer periphery of the cutter blade 25.

As a result, the used injection needle is first brought into a state in which the charging electrode 22 and the cutter blade 25 are short-circuited (for example, the on / off state is repeated), and the applied voltage is instantly discharged to generate high heat. Then, the injection needle is melted and electrically sterilized. At the same time, the injection needle inserted into the groove 25a of the cutter blade 25 is crushed by the rotation of the cutter blade 25 while melting. The sterilized and crushed shattered injection needle falls into the storage chamber 42 of the storage tray 41 and is stored therein. After that, by similarly inserting the used injection needle through the input port 6, all the injection needles are sterilized and crushed and shattered to fall into the storage chamber 42 of the storage tray 41. It is stored.

When the used injection needle is completely inserted into the root, the start button 3 is released and turned off. Then, the power switch 4 is turned off to complete the processing operation. After that, the storage room 42
At a suitable time when a large amount of sterilized and crushed remnants of the injection needle accumulate, the tray drawer 5 is unlocked, and the tray drawer 5 is pulled out from the inside of the casing 2 to the front to be removed and collected in the storage chamber 42. Dispose of the remaining debris as garbage. In this case, the debris is sufficiently sterilized and crushed, and the bacteria etc. are effectively disposed of.

As described above, in this embodiment, after turning on the power switch 4 of the injection needle sterilization and crushing apparatus 1, while pushing the start button 3, the used injection needle contaminated with bacteria is simply discharged from the input port 6. By injecting by pushing, all the injection needles can be processed safely and quickly. In this case, since it is sterilized at once by the battery voltage, simultaneously pulverized by rotation, and no chemicals are used, it can be disposed of at a low cost with a simple configuration.

The present invention is not limited to the example of the above embodiment,
Various modified embodiments are possible as follows. 1) The source that supplies the applied voltage is not limited to the battery, and AC 100 V AC, for example, may be rectified and used. In that case, it is better to use a transformer, a rectifier or the like, which saves the trouble of charging as compared with a battery. 2) It should be noted that the battery checker for the battery may be omitted, and if so, the cost can be reduced to some extent.

[0025]

As described above, according to the present invention, a sterilizing means applies a predetermined voltage to a sterilizing means to sterilize the injection needle, and at the same time, a cutter that is decelerated by a motor to rotate. Since it is crushed by the crushing means having a blade, it can be sterilized at once by voltage, and at the same time, it can be mechanically crushed, and the injection needle can be promptly disposed of with a simple structure. Further, since no chemical is used, the injection needle can be safely disposed of at low cost.
